Caption: Bonobo ape (Pan paniscus) drinking water from a pond. This species of chimpanzee was discovered in 1929. It lives in a matriarchal and egalitarian society where sexual activity between members plays a major role in greeting, conflict resolution and post-conflict resolution, regardless of age and sex. In the wild it is found only in a small area of the Democratic Republic of Congo (DRC) and is considered to be the most endangered of the great apes. It is threatened by habitat loss, the bush meat trade and the trade in live primates. Photographed at the Lola ya Bonobo (Bonobo Paradise) Sanctuary, Democratic Republic of Congo.
